Stage 1: Preparing the milk Gorgonzola is made from pasteurised cow's whole milk which is poured into kettles at a temperature of approximately 30°, adding milk enzymes, rennet and penicillium spores

10
Stage 2: Breaking up the curd Once the mixture has curdled, the curd is broken up and placed on inclined boards to drain the whey

11
Stage 3: Shaping the cheese After a few minutes, the curd is placed in containers known as "fassiroli" or "fascere", of a quantity of approximately 14/15 Kg per cheese, and is then left to rest to allow a further loss of whey

13
Stage 4: Salting After marking, the cheeses are transferred to the so called "purgatory" (cellars featuring a temperature of 20/22 °C and a humidity level of 90/95%). They are then carefully salted on the top, underneath and on the sides and after 3/4 days are sent to the maturing cellars

14
Stage 5: Maturing The cheeses remain in the maturing cellars, featuring a temperature of 2/7 °C and a humidity level of 85/95%, for a period ranging from 50 to 90 days, depending on type (sweet or piquant)

15
Stage 6: Piercing (maturing step) After three to four weeks, the cheeses are pierced. Large metallic (copper) needles penetrate into the cheeses to let the air in, and thus allow the development of the cultures previously introduced in the curd. The air creates the ideal and natural conditions for the development of the penicillium

17
To guaranty quality at the end of the maturing process, the cheese undergoes quality control. They are then cut in two or more pieces and each piece is wrapped in aluminium foil embossed with the “ ” trademark.
